基於SMTP發送一個簡略的郵件
起首,須要一個認證器:
package No001_基於SMTP的文本郵件; import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; public class SimpleAuthenticator extends Authenticator { private String username; private String password; public SimpleAuthenticator(String username, String password) { super(); this.username = username; this.password = password; } protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } }
然後,書寫簡略的發送郵件法式:
package No001_基於SMTP的文本郵件; import java.util.Properties; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class SMTPSimpleMail { public static void main(String[] args) throws AddressException, MessagingException { /* 必須的信息 */ String SMTP_MAIL_HOST = "smtp.163.com"; // 此郵件辦事器地址,自行去所屬郵件查詢 String EMAIL_USERNAME = "[email protected]"; String EMAIL_PASSWORD = "mypassword"; String TO_EMAIL_ADDRESS = "[email protected]"; /* 辦事器信息 */ Properties props = new Properties(); props.put("mail.smtp.host", SMTP_MAIL_HOST); props.put("mail.smtp.auth", "true"); /* 創立Session */ Session session = Session.getDefaultInstance(props, new SimpleAuthenticator(EMAIL_USERNAME, EMAIL_PASSWORD)); /* 郵件信息 */ MimeMessage message = new MimeMessage(session); message.setFrom(new InternetAddress(EMAIL_USERNAME)); message.addRecipient(Message.RecipientType.TO, new InternetAddress(TO_EMAIL_ADDRESS)); message.setSubject("how to use java mail to send email.(Title)(001)"); message.setText("how to use java mail to send email.(Content)"); // 發送 Transport.send(message); System.out.println("不是特殊不利,你可以去查收郵件了。"); } }
各類收件人、抄送人、機密抄送人,怎樣辦
認證器沿用,略。
其實就是設置、追加多個收件人、抄送人、機密抄送人:
package No002_各類發件人收件人抄送人怎樣辦; import java.io.UnsupportedEncodingException; import java.util.Properties; import javax.mail.Address; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class SendMailWithMultiPeople { public static void main(String[] args) throws AddressException, MessagingException, UnsupportedEncodingException { /* 必須的信息 */ String SMTP_MAIL_HOST = "smtp.163.com"; // 此郵件辦事器地址,自行去所屬郵件查詢 String EMAIL_USERNAME = "[email protected]"; String EMAIL_PASSWORD = "mypassword"; String TO_EMAIL_ADDRESS_1 = "[email protected]"; String CC_EMAIL_ADDRESS_1 = "[email protected]"; String BCC_EMAIL_ADDRESS_1 = "[email protected]"; /* 辦事器信息 */ Properties props = new Properties(); props.put("mail.smtp.host", SMTP_MAIL_HOST); props.put("mail.smtp.auth", "true"); /* 創立Session */ Session session = Session.getDefaultInstance(props, new SimpleAuthenticator(EMAIL_USERNAME, EMAIL_PASSWORD)); /* 發件人 */ Address[] senderArray = new Address[1]; senderArray[0] = new InternetAddress("[email protected]", "Nick Huang"); /* 郵件信息 */ MimeMessage message = new MimeMessage(session); message.addFrom(senderArray); message.addRecipient(Message.RecipientType.TO, new InternetAddress(TO_EMAIL_ADDRESS_1)); message.addRecipient(Message.RecipientType.TO, new InternetAddress(CC_EMAIL_ADDRESS_1)); message.addRecipient(Message.RecipientType.CC, new InternetAddress(CC_EMAIL_ADDRESS_1)); message.addRecipient(Message.RecipientType.CC, new InternetAddress(TO_EMAIL_ADDRESS_1)); message.addRecipient(Message.RecipientType.BCC, new InternetAddress(BCC_EMAIL_ADDRESS_1)); message.setSubject("我是一封進修Java Mail的郵件"); message.setText("我是一封進修Java Mail的郵件的內容,請郵件過濾器高抬貴手。"); // 發送 Transport.send(message); System.out.println("不是特殊不利,你可以去查收郵件了。"); } }
發送附件怎樣辦
認證器沿用,略。
發送附件demo:
package No003_發送附件怎樣辦; import java.io.File; import java.io.UnsupportedEncodingException; import java.util.Properties; import javax.activation.DataHandler; import javax.activation.DataSource; import javax.activation.FileDataSource; import javax.mail.Address; import javax.mail.BodyPart; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Multipart; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; public class SendMailWithAttachment { public static void main(String[] args) throws AddressException, MessagingException, UnsupportedEncodingException { /* 必須的信息 */ String SMTP_MAIL_HOST = "smtp.163.com"; // 此郵件辦事器地址,自行去所屬郵件查詢 String EMAIL_USERNAME = "[email protected]"; String EMAIL_PASSWORD = "password"; String TO_EMAIL_ADDRESS_1 = "[email protected]"; /* 辦事器信息 */ Properties props = new Properties(); props.put("mail.smtp.host", SMTP_MAIL_HOST); props.put("mail.smtp.auth", "true"); /* 創立Session */ Session session = Session.getDefaultInstance(props, new SimpleAuthenticator(EMAIL_USERNAME, EMAIL_PASSWORD)); /* 發件人 */ Address[] senderArray = new Address[1]; senderArray[0] = new InternetAddress(EMAIL_USERNAME); /* 郵件信息 */ MimeMessage message = new MimeMessage(session); message.addFrom(senderArray); message.addRecipient(Message.RecipientType.TO, new InternetAddress(TO_EMAIL_ADDRESS_1)); message.setSubject("我是一封進修Java Mail的郵件"); BodyPart bodyPart = new MimeBodyPart(); bodyPart.setText("這是一封進修Java Mail的郵件的內容,請郵件過濾器高抬貴手。"); /* 附件 */ BodyPart attachmentPart1 = new MimeBodyPart(); DataSource source = new FileDataSource(new File("D:/文件壹.txt")); attachmentPart1.setDataHandler(new DataHandler(source)); attachmentPart1.setFileName("=?GBK?B?" + new sun.misc.BASE64Encoder().encode("文件壹.txt".getBytes()) + "?="); BodyPart attachmentPart2 = new MimeBodyPart(); source = new FileDataSource(new File("D:/文件貳.txt")); attachmentPart2.setDataHandler(new DataHandler(source)); attachmentPart2.setFileName("=?GBK?B?" + new sun.misc.BASE64Encoder().encode("文件貳.txt".getBytes()) + "?="); Multipart multipart = new MimeMultipart(); multipart.addBodyPart(bodyPart); multipart.addBodyPart(attachmentPart1); multipart.addBodyPart(attachmentPart2); message.setContent(multipart); // 發送 Transport.send(message); System.out.println("不是特殊不利,你可以去查收郵件了。"); } }
還有,發送HTML郵件
認證器沿用,略。
其實就是告知收件客戶端用HTML解析襯著:
package No004_發送HTML郵件; import java.io.UnsupportedEncodingException; import java.util.Properties; import javax.mail.Address; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Multipart; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeBodyPart; import javax.mail.internet.MimeMessage; import javax.mail.internet.MimeMultipart; public class HowToSendHTMLMail { public static void main(String[] args) throws AddressException, MessagingException, UnsupportedEncodingException { /* 必須的信息 */ String SMTP_MAIL_HOST = "smtp.163.com"; // 此郵件辦事器地址,自行去所屬郵件查詢 String EMAIL_USERNAME = "[email protected]"; String EMAIL_PASSWORD = "password"; String TO_EMAIL_ADDRESS_1 = "[email protected]"; /* 辦事器信息 */ Properties props = new Properties(); props.put("mail.smtp.host", SMTP_MAIL_HOST); props.put("mail.smtp.auth", "true"); /* 創立Session */ Session session = Session.getDefaultInstance(props, new SimpleAuthenticator(EMAIL_USERNAME, EMAIL_PASSWORD)); /* 發件人 */ Address[] senderArray = new Address[1]; senderArray[0] = new InternetAddress(EMAIL_USERNAME); /* 郵件信息 */ MimeMessage message = new MimeMessage(session); message.addFrom(senderArray); message.addRecipient(Message.RecipientType.TO, new InternetAddress(TO_EMAIL_ADDRESS_1)); message.setSubject("若何發送HTML的郵件"); /* 注釋 */ MimeBodyPart bodyPart = new MimeBodyPart(); bodyPart.setContent("<h1>loving you...</h2>", "text/html;charset=gb2312"); /* 封裝郵件各部門信息 */ Multipart multipart = new MimeMultipart(); multipart.addBodyPart(bodyPart); message.setContent(multipart); // 發送 Transport.send(message); System.out.println("不是特殊不利,你可以去查收郵件了。"); } }
要不,來個對象類?
認證器是必定的,沿用,略。
因為須要設置的屬性多且復雜,用個本身人簡略易用的屬生命名,所以來一個設置裝備擺設類
package No005_來一個對象類; import java.io.File; import java.util.ArrayList; import java.util.List; public class MailSenderConfig { private String SMTPMailHost; // 支撐SMTP協定的郵件辦事器地址 /* 用於登錄郵件辦事器 */ private String username; private String password; private String subject; // 題目 private String content; // 內容 private String fromMail; // 顯示從此郵箱收回郵件 private List<String> toMails; // 收件人 private List<String> ccMails; // 抄送人 private List<String> bccMails; // 機密抄送人 private List<File> attachments; // 附件 public MailSenderConfig(String sMTPMailHost, String subject, String content, String fromMail) { super(); SMTPMailHost = sMTPMailHost; this.subject = subject; this.content = content; this.fromMail = fromMail; } public String getSMTPMailHost() { return SMTPMailHost; } public void setSMTPMailHost(String sMTPMailHost) { SMTPMailHost = sMTPMailHost; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getFromMail() { return fromMail; } public void setFromMail(String fromMail) { this.fromMail = fromMail; } public List<String> getToMails() { return toMails; } public void setToMails(List<String> toMails) { this.toMails = toMails; } public List<String> getCcMails() { return ccMails; } public void setCcMails(List<String> ccMails) { this.ccMails = ccMails; } public List<String> getBccMails() { return bccMails; } public void setBccMails(List<String> bccMails) { this.bccMails = bccMails; } public List<File> getAttachments() { return attachments; } public void setAttachments(List<File> attachments) { this.attachments = attachments; } public String getSubject() { return subject; } public void setSubject(String subject) { this.subject = subject; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public void addToMail (String mail) { if (this.toMails == null) { this.toMails = new ArrayList<String>(); } this.toMails.add(mail); } public void addCcMail (String mail) { if (this.ccMails == null) { this.ccMails = new ArrayList<String>(); } this.ccMails.add(mail); } public void addBccMail (String mail) { if (this.bccMails == null) { this.bccMails = new ArrayList<String>(); } this.bccMails.add(mail); } public void addAttachment (File f) { if (this.attachments == null) { this.attachments = new ArrayList<File>(); } this.attachments.add(f); } }
最初,就是對象類的部門,重要擔任幾個工作:依照Java Mail規矩作些初始化舉措、將自界說的屬性設置裝備擺設類翻譯並以Java Mail規矩設置、發送郵件。
還有,須要提下的是,由於對象類所供給的取代設置的屬性無限,更多的情形能夠不知足須要,所以裸露出MimeMessage,在不知足需求的情形開辟者可自行加工設置裝備擺設,而其他部門仍可沿用對象類。

進級下對象類
在現實應用中,發明在批量發送郵件情形下,對象類的支撐欠好,好比發送100封郵件,依照上述對象類的邏輯,每發送一封郵件就樹立一個銜接,那末,100封不就100次了嗎?如許嚴重糟蹋啊。
因而,針對此點作些進級:
認證器是必定的,沿用,略。
